Cationic Heteroleptic Cyclometalated Iridium Complexes with 1-Pyridylimidazo[1,5-alpha]pyridine Ligands: Exploitation of an Efficient Intersystem Crossing

Original language description

A series of phosphorescent cyclometalated heteroleptic iridium(III) phenylpyridinato (ppy) complexes containing luminescent 1-Pyridylimidazo [1,5-.alpha.]pyridine (pip) ligands, namely [Ir(ppy)2 (pip)]+, have been synthesized, characterized and their electrochemical, photophysical and electronic properties studied. Seven X-ray structures have been resolved. Excitation of [[Ir(ppy)2 (pip)]+ in acetonitrile solutions at room temperature results in a dual luminescence, strongly quenched by O2. Four complexes show, in absence of O2, a highenergy emission (assigned to a 3MLLCT transition) with two maxima in the blue region of the visible spectra, and a second structured emission (assigned largely to a 3LC .pi.?.pi.* transition). The electrochemical behaviour of all complexes is also reported.
